The Tropical wave that past through here for several days brought heavy rains to the region. That system is now heading to Florida, which might be the first named storm in May in a while. There is another disturbance over Central America that is trying to make its way up here to the Western Caribbean as well. Thats why the 80 to 90% chances of rain everyday are appearing on weather sites. Here is a tidbit from the NOAA guys.

The GFS model has been predicting during much of the past week that an area of disturbed weather over Central America could act as the seed to get a tropical storm spinning in the Western Caribbean 7 – 12 days from now. Water temperatures there are near 28°C (82°F)—plenty warm enough to support a hurricane. The subtropical jet stream—which is typically located over the Caribbean in May, creating high wind shear that interferes with hurricane development—is predicted to lift northwards by late in the week, creating conditions favorable for tropical cyclone genesis. However, the long range runs of the European model have not been supporting this idea, and Michael Ventrice of The Weather Company, has explained that the GFS model suffers from a known bias in over-predicting tropical cyclone formation in the Western Caribbean this time of year.

I also have been a little nervous about the weather for my trip in June. But, after reading all of the posts in here I have been checking the forecast for each day, then checking the web cams throughout the day. It has put my mind at ease! I was worried that we would have non stop rain, and now I'm feeling pretty secure that while we may get some rain, it's very unlikely to be rain all day, every day!

Today's forecast says Thunderstorms. I've looked at the webcam a few times today, and I haven't seen any rain on the webcams so far today!

I've been here since May 12th. Weather Channel called for 80-100% chance of rain everyday. First evening it poured, one midday it rained for 1-2 hours and we've battled some cloudy sky's off and on. But overall, weather has been gorgeous and nothing like what the forecast was calling for.
